Already searched not much really on the ECU itself or what it does.

Any Advantages of running the knightsport ECU. Car is mostly stock S4 TII only a 3in DP, and intake. I heard it makes the car run more agressive up top. And there is no fuel cut.

I'll do it if I can get the ECU for cheap and its not a bad bolt on.

 

None, zero, zip, those modded ecu's are pretty much useless unless they are tuned and calibrated to your specific car, mods, etc.

 

sounds like stand alone is the best way to go.

 

^^^ For the price some of these ebay people try to charge for them yea... You never know what you're getting from a used "tuner" ecu.
